Interface TileReader

public interface TileReader

Offers a random access interface to the tile data for a raster request.

Implementations are expected to perform better when the tiles are requested in sequential x/y
order (e.g., 0,0; 1,0; 2,0; 0,1; 1,1; 2,1 for 3x2 tile set), though they're required to be able
to return any randomly requested tile, probably by being forced to issue a separate request to
the server or do some caching.
